The City of Coppell Outdoor Warning System consists of nine outdoor warning sirens strategically located throughout the city (see map). As the name indicates, the Outdoor Warning System sirens are designed to warn people who are outside. When you hear the sirens, you should immediately seek shelter inside and seek information.
The sirens may be activated for a number of reasons, including (but not limited to):
When the Outdoor Warning System sirens sound - Seek Shelter & Seek Information:
- Immediately, seek shelter inside,
- Listen to the NOAA weather radio for additional information and specific instructions. (If a NOAA weather radio is not available, try local television or radio stations; please, DO NOT call 9-1-1 to inquire about siren activation.)
Once activated, the sirens will continue sounding a steady tone for three minutes and may continue to sound intermittently during the threat.
The Outdoor Warning System is tested on the first Wednesday of every month at 1:00 p.m.
In the event that inclement weather is in the immediate area or forecast, the test may be postponed until the next scheduled test date.
